The primary goal of this paper is to investigate if there was a bubble in Nasdaq Composite index between 1990 and 2003. To do this, two major different tests are applied. The GSADF test, which can date-stamp the dates with explosiveness and identify if a bubble existed throughout the study period is the first test. In addition to the GSADF, another method that is used to detect the explosiveness is the variance bounds test. Some other tests were also applied in order to have a better understanding about the period with explosiveness in the study period. These tests, includes the chow break test, the abnormal return test, and the variance ratio test, which in themselves are not designed to detect bubbles.
